Introduction
arXivv is the missing data layer for arXiv, built for AI and LLMs. Swap the host, or add an extension to a paper ID.
arXivv serves every arXiv paper as clean Markdown, JSON and plain text, built from one canonical document tree. It is open: no sign-up, no API keys.
Two rules
| Rule | Example | Result |
|---|---|---|
Drop-in: swap arxiv.org for arxivv.org |
https://arxivv.org/abs/1706.03762 |
arXiv’s own response |
Our formats: /<paper>.<format> |
https://arxivv.org/1706.03762.md |
The paper as Markdown |
Formats are md, json and txt. Parts of a paper live under /<paper>/.

Next
- Drop-in compatibility: which hosts are proxied, and how.
- Formats and versions: what each format contains and how caching works.
- Document model: the tree, anchors and aliases.
- First request:
Prefer: waitand async builds. - MCP server: tools for agents.
- API reference: every endpoint, header and error.
